NOVA.16 Multi-reader Access Control Panel
Secura Key’s NOVA.16 multi-reader access control panel introduces new system architecture to Secura Key SK-NET systems. Each panel connects to the local area network and to a peripheral network which supports up to 16 Smart Readers, each controlling a single door or gate. There are no cable home runs from door locations to the control panel; all door connections are made locally at the Smart Reader. Each Smart Reader has a solid-state strike relay, two open collector outputs, and four inputs. The Smart Reader only requires a twisted pair for RS485 data, plus an additional pair for DC power.
